You say you "laid" the paper over the speaker board. Did the cloth also just "lay" on the surface for the speaker board ? If that is the case that may be your problem. You need to apply a glue to the whole front surface of the board before you stretch the cloth over it, and make sure the cloth adheres well to the whole surface after it is stretched tight and secured at the edges.
